Alveolus (singular) is the word used for hollow cavities in anatomy. Consequently, there are different types of alveoli (plural) found throughout the human body. However, alveoli are usually used to describe the small air sacs of the lungs of mammals, and are therefore known more specifically as the pulmonary alveoli. The pulmonary alveolus is a sac roughly 0.2 to 0.5 mm in diameter. These alveoli are located at the ends of air passageways in the lungs.
